help?? I don’t really need answers I just need an explanation on solving these kind of math stuff lol (I did the first two by myself feel free to tell me if I got em wrong)

yes you are right

Step-by-step explanation:

1) Scale 36/27 = 1.33333333   = 1 1/3     Then  20/ 1.33333333 = 15   so yes you are on right track as the shapes are congruently placed side by side for type question and note you have remembered to use the lengths with lengths and widths with widths- just remember to do fold the shapes in your head to determine this or draw dotted line to emphasise the congruency as it exposes each mid point and emphases length fro width  or with triangles hypotenuse from next order of longer side within the triangle to triangle emitting smaller side from diagram on each   2)  Scale = 1.75  For the second one    42/ 24 = 7/4 = 1.75  and 28/1.75 = 16  is also correct
